Static Public Methods

public static of(offsetId: string): ZoneOffset source

Obtains an instance of ZoneOffset using the ID.

This method parses the string ID of a ZoneOffset to return an instance. The parsing accepts all the formats generated by getId, plus some additional formats:

Z - for UTC
+h
+hh
+hh:mm
-hh:mm
+hhmm
-hhmm
+hh:mm:ss
-hh:mm:ss
+hhmmss
-hhmmss

Note that ± means either the plus or minus symbol.

The ID of the returned offset will be normalized to one of the formats described by getId.

The maximum supported range is from +18:00 to -18:00 inclusive.

Params:

Name	Type	Attribute	Description
offsetId	string		the offset ID, not null

Return:

ZoneOffset

the zone-offset, not null

Throw:

*	DateTimeException if the offset ID is invalid

public static ofHours(hours: number): ZoneOffset source

Params:

Name	Type	Attribute	Description
hours	number

Return:

ZoneOffset

public static ofHoursMinutes(hours: number, minutes: number): ZoneOffset source

Params:

Name	Type	Attribute	Description
hours	number
minutes	number

Return:

ZoneOffset

public static ofHoursMinutesSeconds(hours: number, minutes: number, seconds: number): ZoneOffset source

Params:

Name	Type	Attribute	Description
hours	number
minutes	number
seconds	number

Return:

ZoneOffset

public static ofTotalMinutes(totalMinutes: number): ZoneOffset source

Params:

Name	Type	Attribute	Description
totalMinutes	number

Return:

ZoneOffset

public static ofTotalSeconds(totalSeconds: number): ZoneOffset source

Params:

Name	Type	Attribute	Description
totalSeconds	number

Return:

ZoneOffset

Public Constructors

public constructor(totalSeconds: number) source

Params:

totalSeconds	number

Public Methods

public adjustInto(temporal: Temporal): Temporal source

Adjusts the specified temporal object to have the same offset as this object.

This returns a temporal object of the same observable type as the input with the offset changed to be the same as this.

The adjustment is equivalent to using Temporal#with passing ChronoField#OFFSET_SECONDS as the field.

In most cases, it is clearer to reverse the calling pattern by using Temporal#with:

  // these two lines are equivalent, but the second approach is recommended
  temporal = thisOffset.adjustInto(temporal);
  temporal = temporal.with(thisOffset);

This instance is immutable and unaffected by this method call.

Params:

Name	Type	Attribute	Description
temporal	Temporal		the target object to be adjusted, not null

Return:

Temporal

the adjusted object, not null

Throw:

*	DateTimeException if unable to make the adjustment
*	ArithmeticException if numeric overflow occurs

public compareTo(other: ZoneOffset): number source

Compares this offset to another offset in descending order.

The offsets are compared in the order that they occur for the same time of day around the world. Thus, an offset of +10:00 comes before an offset of +09:00 and so on down to -18:00.

The comparison is "consistent with equals", as defined by Comparable.

Params:

Name	Type	Attribute	Description
other	ZoneOffset	nullable: false	the other date to compare to, not null

Return:

number

the comparator value, negative if less, postive if greater

Throw:

*	NullPointerException if other is null

public equals(obj: *): boolean source

Checks if this offset is equal to another offset.

The comparison is based on the amount of the offset in seconds. This is equivalent to a comparison by ID.

Override:

ZoneId#equals

Params:

Name	Type	Attribute	Description
obj	*		the object to check, null returns false

Return:

boolean

true if this is equal to the other offset

public get(field: TemporalField): number source

Gets the value of the specified field from this offset as an int.

This queries this offset for the value for the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The OFFSET_SECONDS field returns the value of the offset. All other ChronoField instances will throw a DateTimeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

Params:

Name	Type	Attribute	Description
field	TemporalField		the field to get, not null

Return:

number

the value for the field

Throw:

*	DateTimeException if a value for the field cannot be obtained
*	ArithmeticException if numeric overflow occurs

public getLong(field: TemporalField): number source

Gets the value of the specified field from this offset as a long.

This queries this offset for the value for the specified field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The OFFSET_SECONDS field returns the value of the offset. All other ChronoField instances will throw a DateTimeException.

Params:

Name	Type	Attribute	Description
field	TemporalField		the field to get, not null

Return:

number

the value for the field

Throw:

*	DateTimeException if a value for the field cannot be obtained
*	ArithmeticException if numeric overflow occurs

public hashCode(): number source

Override:

ZoneId#hashCode

Return:

number

public id(): string source

Override:

ZoneId#id

Return:

string

public query(query: TemporalQuery): * source

Queries this offset using the specified query.

This queries this offset using the specified query strategy object. The TemporalQuery object defines the logic to be used to obtain the result. Read the documentation of the query to understand what the result of this method will be.

The result of this method is obtained by invoking the TemporalQuery#queryFrom method on the specified query passing this as the argument.

Params:

Name	Type	Attribute	Description
query	TemporalQuery		the query to invoke, not null

Return:

*	the query result, null may be returned (defined by the query)

Throw:

*	DateTimeException if unable to query (defined by the query)
*	ArithmeticException if numeric overflow occurs (defined by the query)

public rules(): ZoneRules source

Gets the associated time-zone rules.

The rules will always return this offset when queried. The implementation class is immutable, thread-safe and serializable.

Override:

ZoneId#rules

Return:

ZoneRules

the rules, not null

public toString(): string source

Override:

ZoneId#toString

Return:

string

public totalSeconds(): number source

Return:

number
